Description

本発明は、概して、液圧マウント装置に関する。 The present invention generally relates to hydraulic mounting devices.

従来から、振動を防止しながら振動源を支持するマウント（装着器）がある。こうしたマウントの周知の応用には、自動車の構成要素の支持がある。こうしたマウントは典型的には、エンジン振動を防止するとともに、車両フレームすなわち車体構造に対するエンジンおよびそれに接続されたパワートレイン要素の運動を制御するよう動作する。エンジンやパワートレインのマウントの多くの応用においては、ある周波数の振動を選択的に防止するよう、マウント器の減衰特性が変化することが望ましい。 Conventionally, there is a mount that supports a vibration source while preventing vibration. A well-known application of such mounts is the support of automotive components. Such mounts typically act to prevent engine vibration and to control the movement of the engine and its connected powertrain elements with respect to the vehicle frame or body structure. In many applications of engine and powertrain mounts, it is desirable to change the damping characteristics of the mounter to selectively prevent vibrations of a certain frequency.

このような液圧マウント装置の一つが米国特許第６０８２７１８号明細書に開示されている。液圧マウント装置は、中心軸上に配置される上側部分および下側部分を有し、ハウジングチャンバを形成する、ハウジングを有する。パーティション部材が、ハウジングチャンバをポンピングチャンバと収容チャンバとに分割するよう、ハウジングチャンバ内に配置されている。ポンピングチャンバは、上側部分とパーティション部材との間に延設される。収容チャンバは、下側部分とパーティション部材との間に延設される。デカップラが、ポンピングチャンバと収容チャンバとを分離するパーティション部材に取り付けられる。エラストマー材料の可動部材が、ポンピングチャンバ内に配置されるとともにデカップラに取り付けられている。 One such hydraulic mounting device is disclosed in US Pat. No. 6,082,718. The hydraulic mounting device has a housing that has an upper portion and a lower portion that are located on the central axis and forms a housing chamber. Partition members are arranged within the housing chamber to divide the housing chamber into a pumping chamber and a containment chamber. The pumping chamber extends between the upper portion and the partition member. The containment chamber extends between the lower portion and the partition member. A decoupler is attached to a partition member that separates the pumping chamber and the containment chamber. A movable member of elastomeric material is placed in the pumping chamber and attached to the decoupler.

米国特許第６０８２７１８号明細書U.S. Pat. No. 6,082,718

典型的には、ユーザが可動部材の剛性を変更するために金属インサートが可動部材内に埋設される。しかしながら、金属インサートを可動部材内に配置することによって、液圧マウント装置の製造コストが増加してしまう。さらに、エラストマー材料および金属インサートは、液圧マウント装置内の流体と化学的に反応する可能性があり、したがって、液圧マウント装置の寿命を短くしてしまうおそれがある。 Typically, a metal insert is embedded in the movable member in order for the user to change the stiffness of the movable member. However, by arranging the metal insert in the movable member, the manufacturing cost of the hydraulic mounting device increases. In addition, elastomeric materials and metal inserts can chemically react with the fluid in the hydraulic mounting device, thus shortening the life of the hydraulic mounting device.

本発明は、液圧着装置の可動部材への金属インサートの必要性をなくす液圧ダンパを提供することを目的とする。また、本発明は、可動部材が正圧状態において圧縮プレートへとまた真空状態においてキャップへと押し出されてしまうことを防止することを目的とする。さらにまた本発明は、液圧マウント装置の寿命を向上するよう、可動部材におけるエラストマー材料（例えばゴム）の量をさらに低減することを目的とする。 An object of the present invention is to provide a hydraulic damper that eliminates the need for a metal insert into a movable member of a liquid crimping device. Another object of the present invention is to prevent the movable member from being pushed out to the compression plate in the positive pressure state and to the cap in the vacuum state. Furthermore, it is an object of the present invention to further reduce the amount of elastomeric material (eg rubber) in the movable member so as to extend the life of the hydraulic mounting device.

本発明の一の面では、中心軸上に配置される上側部分および下側部分を有し、ハウジングチャンバを形成する、ハウジングを有する液圧マウント装置を提供する。パーティション部材が、ハウジングチャンバをポンピングチャンバと収容チャンバとに分割するよう、ハウジングチャンバ内に配置されている。ポンピングチャンバは、上側部分とパーティション部材との間に延設される。収容チャンバは、下側部分とパーティション部材との間に延設される。デカップラが、ポンピングチャンバと収容チャンバとを分離するパーティション部材に取り付けられる。可動部材が、ポンピングチャンバ内に配置され、デカップラに取り付けられる。可動部材は、追加的な減衰力を与えるためにデカップラに固定される非エラストマー重合体シートである。可動部材は、ハウジングチャンバにおける体積変化に応じてポンピングチャンバ内で撓む。可動部材は、ポンピングチャンバに追加的な減衰力を与える。液圧マウント装置は、ポンピングチャンバ内においてデカップラから間隔を空けて配置されるキャップを更に備え、可動部材をキャップとデカップラとの間に固定する。キャップは、可動部材から軸方向に間隔を空けて配置される下側プレートと、可動部材と係合して可動部材をデカップラに固定するよう、下側プレートからデカップラに向かって外側に環状に延設される突出部と、を有する。キャップは、下側プレートから外側にかつ中心軸と平行に突出部とは反対方向に環状に延設されるリブを有する。リブは、中心軸に面する内面と内面とは反対側にある外面とを有し、内面と下側プレートとの間でポンピングチャンバと流体連通状態に配置されるポケットが形成される。 One aspect of the invention provides a hydraulic mounting device with a housing that has an upper portion and a lower portion that are located on a central axis and forms a housing chamber. Partition members are arranged within the housing chamber to divide the housing chamber into a pumping chamber and a containment chamber. The pumping chamber extends between the upper portion and the partition member. The containment chamber extends between the lower portion and the partition member. A decoupler is attached to a partition member that separates the pumping chamber and the containment chamber. Movable members are placed in the pumping chamber and attached to the decoupler. The movable member is a non-elastomer polymer sheet that is fixed to the decoupler to provide additional damping force. The movable member bends in the pumping chamber in response to a change in volume in the housing chamber. The movable member provides additional damping force to the pumping chamber. The hydraulic mounting device further comprises a cap that is spaced apart from the decoupler in the pumping chamber and secures the movable member between the cap and the decoupler. The cap extends in an annular shape from the lower plate toward the decoupler so as to engage with the lower plate arranged at an axial distance from the movable member and fix the movable member to the decoupler. It has a protrusion to be provided. The cap has ribs that extend outward from the lower plate and in an annular direction parallel to the central axis and in the direction opposite to the protrusion. The rib has an inner surface facing the central axis and an outer surface opposite to the inner surface, and a pocket is formed between the inner surface and the lower plate so as to be arranged in a fluid communication state with the pumping chamber.

本発明の他の面では、液圧マウント装置のためのデカップラを提供する。デカップラは、中心軸上に配置され、支持部材上端部と支持部材下端部との間に延設される支持部材を有する。可動部材は、中心軸上に配置され、中心軸から支持部材上端部へと径方向外側に延設され、支持部材上端部に取り付けられる。可動部材は、追加的な減衰力を与えるためにデカップラに固定される非エラストマー重合体シートである。 Another aspect of the invention provides a decoupler for a hydraulic mounting device. The decoupler has a support member that is arranged on the central axis and extends between the upper end of the support member and the lower end of the support member. The movable member is arranged on the central axis, extends radially outward from the central axis to the upper end of the support member, and is attached to the upper end of the support member. The movable member is a non-elastomer polymer sheet that is fixed to the decoupler to provide additional damping force.

本発明の他の利点は、添付図面を参照して以下の詳細な説明からより理解され、明らかとなろう。 Other advantages of the present invention will be better understood and apparent from the following detailed description with reference to the accompanying drawings.

図面を参照して、本発明の一の実施形態に基づいて構成された液圧マウント装置２０を、概略的に図１に示す。図面では、対応する部品には同じ符号を付している。典型的には、液圧マウント装置２０は、車両の構成要素例えば車両のフレーム上に配置されるエンジンを支持するよう用いられる。なお、液圧マウント装置２０を、種々の他の振動源を支持するよう用いることができることは理解されよう。 With reference to the drawings, a hydraulic mounting device 20 configured based on one embodiment of the present invention is schematically shown in FIG. In the drawings, the corresponding parts are labeled with the same reference numerals. Typically, the hydraulic mounting device 20 is used to support an engine that is placed on a vehicle component, eg, a vehicle frame. It will be appreciated that the hydraulic mounting device 20 can be used to support a variety of other sources of vibration.

図１に概略的に示す通り、液圧マウント装置２０は下側部分２４および上側部分２６を有するハウジング２２を有する。下側部分２４および上側部分２６は、中心軸Ａ上に配置され、互いから軸方向に間隔を空けて配置される。略管状の壁２８が、中心軸Ａ上に配置され、下側部分２４を上側部分２６に接続するよう、下側部分２４と上側部分２６との間に延設されており、これにより、下側部分２４と上側部分２６と壁２８との間に延設されるハウジングチャンバ３０，３２，３４を形成している。 As schematically shown in FIG. 1, the hydraulic mounting device 20 has a housing 22 having a lower portion 24 and an upper portion 26. The lower portion 24 and the upper portion 26 are arranged on the central axis A and are arranged at intervals in the axial direction from each other. A substantially tubular wall 28 is located on the central axis A and extends between the lower portion 24 and the upper portion 26 so as to connect the lower portion 24 to the upper portion 26, thereby lowering. Housing chambers 30, 32, 34 are formed extending between the side portion 24, the upper portion 26, and the wall 28.

下側部分２４は、略椀形状を有し、下側部分閉口端部３６と下側部分開口端部３８との間で中心軸Ａの回りに環状に延設される。下側部分リップ４０が、壁２８と係合するよう、下側部分開口端部３８から径方向外側に（中心軸Ａに対して垂直に）延設される。下側部分２４は、中心軸Ａ上に配置される円筒状のカラー４２を有する。カラー４２は、下側部分閉口端部３６から外側にかつ中心軸Ａの回りに遠位側端部４４へと環状に延設される。カラー４２は、ハウジング２２を車両に取り付けるための、下側部分２４と遠位側端部４４との間で中心軸Ａに沿って延設される略円筒状の下側部分ボア４６を形成する。 The lower portion 24 has a substantially bowl shape and extends in an annular shape around the central axis A between the lower portion closed end portion 36 and the lower portion open end portion 38. The lower portion lip 40 extends radially outward (perpendicular to the central axis A) from the lower portion open end 38 so as to engage the wall 28. The lower portion 24 has a cylindrical collar 42 that is located on the central axis A.

図３からよく分かる通り、可動部材９０は、追加的な減衰力を与えるためにデカップラ７４に固定される非エラストマー重合体（ポリマー）シートである。略円形状の可動部材９０は、中心軸Ａ上に延設される外周部１１８を有する打抜き重合体シート（ｄｉｅ ｃｕｔ ｐｏｌｙｍｅｒ ｓｈｅｅｔ）である。可動部材９０が非エラストマーポリマーである場合、可動部材９０と磁気粘性流体との間の化学的反応を最小限とでき、したがって、デカップラ７４および液圧マウント装置２０の動作寿命を長くすることができる。 As can be clearly seen from FIG. 3, the movable member 90 is a non-elastomer polymer sheet that is fixed to the decoupler 74 to provide additional damping force. The substantially circular movable member 90 is a punched polymer sheet (die cut polymer sheet) having an outer peripheral portion 118 extending on the central axis A. When the movable member 90 is a non-elastomer polymer, the chemical reaction between the movable member 90 and the ferrofluid can be minimized, and thus the operating life of the decoupler 74 and the hydraulic mounting device 20 can be extended. ..

より具体的には、研究により、磁気粘性流体に含まれるエトキシル化アミン、プロピレングリコールおよび他の添加物が液圧マウント装置２０のエラストマー材料と反応する傾向があることが分かった。この化学的反応により、液圧マウント装置２０内において気体が発生して、圧力上昇が生じ、液圧マウント装置２０の本来の機能的性能を妨げるおそれがある。さらにまた、この反応により磁気粘性流体化合物において、二量体や三量体が形成され、磁気粘性流体化合物において形成されるチキソトロピーネットワークを分断し、磁気的反応粒子（ｍａｇｎｅｔｉｃ ｒｅｓｐｏｎｓｉｖｅ ｐａｒｔｉｃｌｅ）を磁気粘性流体化合物から沈殿させ、その結果、磁気粘性流体合成物の寿命が短くなる。可動部材９０が非エラストマーポリマーであることにより、本発明では、可動部材９０と磁気粘性流体との間の化学的反応を最小限とでき、したがって、磁気的反応粒子が磁気粘性流体化合物から沈殿することを防止でき、デカップラ７４および液圧マウント装置２０をより長い期間にわたって動作させることができる。 More specifically, studies have shown that ethoxylated amines, propylene glycol and other additives contained in ferrofluids tend to react with the elastomeric material of the hydraulic mounting device 20. Due to this chemical reaction, gas is generated in the hydraulic mounting device 20 to cause a pressure increase, which may interfere with the original functional performance of the hydraulic mounting device 20. Furthermore, this reaction forms dimers and trimerics in the ferrofluid compound, disrupts the thixotropic network formed in the ferrofluid compound, and separates the magnetic reaction particles (magnetic reactive participants) into the ferrofluid fluid. It precipitates from the compound, resulting in a shorter life of the ferrofluid composite. The non-elastomer polymer of the moving member 90 allows the present invention to minimize the chemical reaction between the moving member 90 and the ferrofluid, thus precipitating the ferrofluid particles from the ferrofluid compound. This can be prevented and the elastomer 74 and the hydraulic mounting device 20 can be operated for a longer period of time.

略円形状のキャップ（蓋部材）１２０が、ポンピングチャンバ３０内においてデカップラ７４から間隔を空けて配置され、これにより、可動部材９０をキャップ１２０とデカップラ７４との間に固定することができる。キャップ１２０は、可動部材９０から軸方向に間隔を空けて配置される略円形状の下側プレート１２２を有する。突出部１２４が、可動部材９０と係合して可動部材９０をデカップラ７４に固定するよう、下側プレート１２２からデカップラ７４に向かって外側に延設される。可動部材９０をデカップラ７４に固定するよう、突出部１２４を中心軸Ａの回りに環状に延設することができることを記載しておく。下側プレート１２２は、磁気粘性流体がキャップ１２０を通って流れることができるよう、キャップ１２０を貫通して延びる少なくとも１つのオリフィス（孔）１２６を有する。なお、少なくとも１つのオリフィス１２６は、磁気粘性流体がキャップ１２０を通って流れるのを可能にする径方向および周方向に互いから間隔を空けて配置される複数のオリフィス１２６を有することもできることは理解されよう。 The substantially circular cap (lid member) 120 is arranged in the pumping chamber 30 at intervals from the decoupler 74, whereby the movable member 90 can be fixed between the cap 120 and the decoupler 74. The cap 120 has a substantially circular lower plate 122 that is arranged at intervals in the axial direction from the movable member 90.

The cap 120 has a pocket 134 that is arranged in a fluid communication state with the pumping chamber 30. The pocket 134 extends between the inner surface 130 of the rib 128 and the lower plate 122. The outer surface 132 is chamfered in the vicinity of the outer peripheral portion 118 of the movable member 90 so as to form a conduit 136 extending in an annular shape around the central axis A. An O-ring 138 made of an elastomer material is arranged in the conduit 136 and extends in an annular shape around the central axis A so as to be in a sealed engagement state with the outer surface 132 and the outer peripheral portion 118 of the movable member 90. The decoupler has a compression plate 140 located on the opposite side of the cap 120, adjacent to the movable member 90 and in the recess 88 at a distance from the movable member 90, so as to limit the movement of the movable member 90. .. In other words, the only rubber component within the decoupler is the O-ring 138, which provides a sealing function between the cap 120 and the movable member 90. In addition, the movable member 90 made of a non-elastomer polymer has greater rigidity than rubber, reduces the need for a metal insert, and realizes a lower cost than a member using an elastomer movable member having a metal insert.

In other words, the signal generated by the strain gauge sensor 142 allows the user to measure the frequency component of the movable member 90 of the decoupler 74. The compression plate 140 has a passage 146 extending through the compression plate 140 to accommodate the lead wire 144 so that the lead wire 144 can extend through the decoupler 74. It should be noted that the strain gauge sensor 142 may have a wireless module that can wirelessly transfer the signal of the strain gauge sensor 142 to the user instead of the lead wire 144.

動作時において、液圧マウント装置２０が励起運動（例えば振動運動）を受けると、可撓体５６が変形し、これにより、ポンピングチャンバ３０と流体チャンバ３２と補償チャンバ３４との体積変化が生じる。その結果、可動部材９０が体積変化に応じてポンピングチャンバ３０内で撓む。可動部材９０がポンピングチャンバ３０内で撓むと、励起運動に応じた追加的な減衰力を可動部材９０がポンプチャンバ３０に提供する。可動部材９０がポンピングチャンバ３０内において撓むと、歪みゲージセンサ１４２が可動部材９０の記録および監視を行い、可動部材９０の移動の関数として可動部材９０への荷重を測定する。歪みゲージセンサ１４２によって生成される信号は、リード線１４４を介してユーザへと伝達され、これにより、ユーザがデカップラ７４の可動部材９０の振動数成分を測定することができる。 When the hydraulic mounting device 20 receives an excitation motion (for example, a vibration motion) during operation, the flexible body 56 is deformed, which causes a volume change between the pumping chamber 30, the fluid chamber 32, and the compensation chamber 34. As a result, the movable member 90 bends in the pumping chamber 30 in response to the volume change. When the movable member 90 bends in the pumping chamber 30, the movable member 90 provides the pump chamber 30 with an additional damping force in response to the excitation motion. When the movable member 90 bends in the pumping chamber 30, the strain gauge sensor 142 records and monitors the movable member 90, and measures the load on the movable member 90 as a function of the movement of the movable member 90. The signal generated by the strain gauge sensor 142 is transmitted to the user via the lead wire 144, which allows the user to measure the frequency component of the movable member 90 of the decoupler 74.
